SILK- -DOUBLER.

SPECIFICATION forming part of Letters Eatent No. 661,209, dated November6, 1900.

Application filed June 26, 1900. Serial No. 21.625. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH DUFFY, a citizen of the United States,residing at No. 48 lVayne avenue, in the city of Paterson, in the.county of Passaic and State of New Jersey, have invented certain new anduseful Improvements in Silk-Doublers, of which the following is aspecification, reference being had therein to the accompanying drawings.

The object of my invention is to increase the capacity of a silk-doublerby operating more spindles on a machine of a given size than is done bythe machines as now constructed and in common use and by the newarrangement, construction, and combination of parts to prod ucea machinethat willdouble the production without increasing the power, that willsave time in the starting up and doffing, that will work a saving offifty per cent. in floor-space, and that will by reason of its peculiarstop-motion and means for adjusting and regulating the traverse asrequired greatly facilitate the process of doubling in the manufactureof silk.

My invention relates only to the machine known as the doubler, themachine to which the bobbins containing the yarn without any twist comefrom the first Winder in single strands, there to be laid together, twoor more, as the case may call for, before going to the spinningmachineto be spun. For the past sixty years the machines used for this purposehave had the bobbins lying horizontally six and one-half inches apart,while I mount the bobbins on vertical spindles about three and one-halfinches apart and have adapted a novel construction and arrangement ofthe various other parts of the driving and automatic stop mechanisms,which I claim produces a new and useful silk-doubler. My machine neitherspins nor twists, being a plain silk-doubler, and .does not belong tothe class of machines that have spinning and twisting devices and whichcannot fill the place of a doubler pure and simple. The .doubler stands.in the order of manufacture between the winder and spinner for tram andbetween the spinner and the twister for organzine.

The inventionconsists of aiframe on which the spindles are operated in avertical posi- .tion, which permits of a closer arrangement thereof,means for driving and stopping the spindles, a vertical traverse devicefor dis tribnting the thread, and means for adjusting and regulating thetraverse, all of which will be more fully described hereinafter andclaimed.

In the drawings, in which similar letters of reference indicate likeparts, Figure lis a side view of my vertical doubler, showing one sideof the frame in Working order and on the other side the operation ofvarious parts caused by the breaking of one or more threads, and alsoshowing the device for adjusting and regulating the traverse. Fig. 2 isa top view of part of doubler, one side of irame'being in Working order,the other side showing the fallers and stopping devices.

In the drawings, A is the frame of the doubler; B, the bobbins; S, thethreads, and C the spindles. A bracket D is secured to the table-board aon each side of the frame A and carries the bars (Z (I, over which thethreads pass to be wound upon the bobbins, the distribution of thethread being regulated by the traverse-bars E E, one of which issituated on each side of the frame. The traverse-bars E are providedwith a longitudinal groove, in which are suitably secured threadguidese, of porcelain or other proper mate rial, and are lifted by the rockerF, which is located on the rocker-shaft f, and the oscillation of whichis governed by the adjustable connecting-rod 0, having the parts 0, o,and o to regulate the traverse. Each end of the rocker F is providedwith a roller f". The dotted lines (indicated by asmall letters)represent a broken thread. The spindle 0 has a lower portion 0, on whichis a shoulder c, and an upper portion, in which is located a spring 0 IThe spindles are mounted in the rail 0. and are operated by the belt Nand the frictiom pulleys G,the saidbelt passingaround the end pulleys Gand the friction-pulleys G, but one friction-pulley being required forevery four spindles. To insure more friction, idlers g may be employed,as required. The stopping device L is pivoted on the pinZ and has astraight end Z and the curved end P, which is provided with a roller 1the spiral spring M pressing against the straight end I, thereby causingthe curved end 1 to go between the belt and the spindle, thus stoppingthe spindle whenever a thread breaks. .On the stand I are two uprights2' and i, in which are respe-ctively pivoted the lever K and the fallersH. The fallers have an eye it and a hooked end h. A pin 77, passesthrough the eye It and through the stand 2' to secure the fallers inplace. The lever K, which is pivoted in the upright 't", has an upturnedend 7a, a nose in, and a straight portion 70 The hooked ends of thefallers I-I rest on the threads S when the machine is in operation, andthe spiral spring M presses the straight end 1 of the stopper L againstthe end 70 of the lever K, and when the thread breaks the faller dropson the upturned end of the lever K, which releases the lever fromengagement with the end of the stopper L, and it is forced laterally,throwing the curved end of the stopper L between the belt and thespindle, thus stopping the revolution of the spindle.

In doublers now in use the spindles are mounted in a horizontal positionon the frame and are usually six and one-half inches apart, whereas byhaving them in a vertical position I can have them three and one-halfinches apart, so that the saving in floor-space and the increase in thecapacity of the machine are obvious. As is shown in the drawings, anynumber of fallers may be used. At the speed these spindles are run I canuse good wrought-iron, the feet being hardened in potash and brine. Theshortness of the spindle and the spring attachment make it handy formounting and dofling the bobbins. The spindles running in a verticalposition require less power than if running in ahorizontal position.

In Fig. 2 of the drawings, 6 is a lifting-bar having a shoulder e Withthis description of my invention,what I claim is- In a silk-doubler, thevertically-mounted spindles and the belt and pulleys for driving thesame, in combination with astop-lever, a spring adapted to press againstthe outer end of the lever causing the innerend to pass between the beltand spindle, a vertically-tilting lever the inner end of which isadapted to engage the spring-actuated end of the stoplever, and fallerspivot-ally mounted above said vertically-tilting lever-and adapted tofall upon the outer end thereof, it unsupported, thereby causing theinner end to be raised and permitting the spring-actuated end of thestop-lever to be pressed laterally forcing the inner end of the samebetween the belt and the spindle,substantially as set forth.
